[Lazarus] How to tell debugger what executable to use ?

[Martin Frb]

I dont know the answer, sa I do not have that scenario myself.

It would help, if you can specify which commands, to send to gdb, if you 
run gdb outside lazarus.

In Lazarus, There is also Menu: "Run" > "Run Parameter" which allaws to 
set the "Host application". That is the exe gdb should debug, e.g. if 
your project is a library, and you nneed to specify an exe that loads 
the library.

-----------------
No idea about "monitor".
But the IDE has 2 "developer" modes.(They are for developing the gdb 
integration. They allow directly sending commands to GDB, without 
checking them. However sending the wrong command, and your IDE/GDB 
communication breaks, and you loose the debug session.
Sending commands only works, when the app is paused.

You need to define
DBG_WITH_DEBUGGER_DEBUG
DBG_WITH_GDB_WATCHES
and then recompile the IDE

DBG_WITH_DEBUGGER_DEBUG
   There will be an TEdit at the bottom of the "Debug Output" Window. It 
can be used to send command

DBG_WITH_GDB_WATCHES
   You can enter special watches, that will execute. They must start 
with a ">" (You can use the eval/modify window)
 >ptype ToOo


Warning: In both cases, sending any command that performs 
running/stepping, and the IDE willloose the session.
